Help, I have a customer asking if our shop conforms to IPC-a-610 class 2 specs. He is asking if our Humidity is kept under 40% and if we have a particle count under 5MG......where can I find info in the IPC spec on humidty and particle count in the

We have a customer enquiry that requires PCB assemblies to be cleaned to J-STD-001 / -004 class 3. We use both water based and no clean process chemistries. No clean flux residues are not permitted and would therefore have to be cleaned. My question

Definitely better than foam!! I personally love the sonoteks. They do not really use a "nozzle" by the way. The flux is pooled on U.S. head and it atomizes it and then you have air spray to form proper spray pattern, If you are using Water soluble

Degassing - the air in the void above the electrolyte expands, or in some cases the electrolyte vapourises, blowing the top of the cap from the base. Sometimes electrolyte can also leak out around the base seal. This is also a failure as the cap wo

I am having issues with parts falling off a double sided board in the Vitronics but not in Heller oven. The oven profiles are as close to each other as I can get them. Does the Vitronics have more air flow? The Heller is an older oven and the chain d

2-3mm would seem close enough to affect the air flow and I was thinking it could be displacing the qfn. However, if you ran a failed board back through reflow and it was functional after that, I'd put my money on insufficient reflow. I suppose it's

Having problem with a 2X50 SCKT Strip PTH component(fine pitch) bridging on the wave. The PCB runs in wave pallets. Just wanting to know what successful findings have been done to eliminate bridging? Pallet angles? Copper or titanium inserts? Air kni

Good Morning All, We are looking at new equipment for reworking BGA components that is RoHS capable. I wanted to get a feel for what others in the industry are using and get some feedback good or bad on these systems. We are currently using an Air

I have seen point-to-point soldering iron tip robots in action at a number of factories. The problem is repeatability at delivering good solder joints. Consider a small selective solder machine, the nozzle type: www.ace-protech.com www.air-vac-eng.c

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM
